Self-propelled mortars are 1 of the most effective and versatile forms of close infantry support and intermediate fire vehicles. Open-type structures specified as [French Griffin MEPAC](article:1046640) or [Switzerland Mörser 16](article:1020535) due to the expanding threat of various types of combat agents dropped from drones appear to be non-perspective.

Examples of specified structures are [Polish M120 Cancer](article:1033516), [Israeli Crossbow 120](article:1037988) or [Finnish Nemo](article:1041784).
